Laser Safety
The output of the CO2 engraving laser is fully contained in a Class 1 enclosure during normal operation. The laser
cabinet has a safety interlock switch that deactivates the laser if the door is opened during operation, and no special
precautions are necessary to operate the high power laser safely. However, the output beam of the Alignment Laser
(visible red diode laser) is accessible to the operator during normal operation, giving the total system an overall rating
of Class 3R. While this device employs the same technology as a handheld laser pointer, it is potentially hazardous if
its beam is directed into the eye.
GENERAL OPERATION PRECAUTIONS
The laser operator should observe the following:
•
NEVER operate the machine with any of the panels removed. Be aware that removal of any portion of
the cabinet will expose a Class 4 laser system and greatly increase the risk of injury and/or fire. Personal
injury and fire risks are especially pronounced if the machine is operated with the bottom panel removed.
Remember that the CO2 laser beam is invisible!
•
NEVER engrave or cut any material containing PVC or vinyl. These materials (along with other chlorine/
chloride containing materials) produce a corrosive vapor that is extremely harmful to humans and will
destroy your machine. Your warranty will be void if your machine is damaged by corrosion from engraving
or cutting PVC or vinyl.
•
NEVER engrave or cut any unknown material. The vaporization/melting of many materials, including but
not limited to PVC and polycarbonates, can give off hazardous fumes. Please refer to the MSDS sheet from
the material manufacturer to determine the response of any work material to extreme heat (burning/fire
hazard).
•
NEVER operate your machine unattended. There is a significant risk of fire if the machine is set improperly,
or if the machine should experience a mechanical or electrical failure while operating.
•
ALWAYS use the air assist, especially while vector cutting. Vector cutting movements are relatively slow
and apply an extremely large amount of heat to the work piece. This buildup of heat can cause a significant
fire risk.
•
DO NOT disassemble the machine or remove any of its protective covers while the unit is plugged in.
•
DO NOT defeat the door interlock.
•
DO NOT look into the beam of the Alignment Laser (visible red diode laser)
5TH GEN HOBBY LASER USER’S MANUAL
•
7
DO NOT operate the Alignment Laser without the focus lens in place. The unfocused beam can be reflected
out of the chassis.
•
NEVER operate the machine without a properly operating ventilation system. Most materials produce an
irritating smoke when engraved. Some materials, including but not limited to paint, varnish, composition
board and plastics, produce compounds that can be harmful if concentrated.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein
may result in hazardous radiation exposure.
The standard reference for laser safety is the American Standard for the Safe Use of Lasers, Z136.1-2000, developed
by the American National Standards Institute (ANSI). This reference is the basis for many of the federal regulations
for laser and laser system manufacturers, and for the Occupational Safety and Health Administration (OSHA) laser
safety guidelines. It contains detailed information concerning proper installation and use of laser systems. While
the ANSI standard itself does not have the force of law, its recommendations, including warning signage, training,
and the designation of a laser safety officer, may be compulsory under local workplace regulations when operating
laser systems above Class I. It is the operator’s responsibility to ensure that the installation and operation of the Full
Spectrum Laser Hobby Advanced Laser System is performed in accordance with all applicable laws. Copies of ANSI
Standard Z136.1-2000 are available from:

Electrical Safety
The AC input power to the Full Spectrum HL40-5g is potentially lethal and is located on the far right within the cabinet.
•
DO NOT open any of the machine’s access panels while the unit is plugged in. Opening a
panel may expose the operator to the unit’s AC input power.
•
DO NOT make or break any electrical connections to the system while the unit is turned on.
•
DO NOT access the electronics area with hands or tools unless the unit is disconnected
from power.
The power supply is capable of outputting DC 20,000V at up to 20mA—always make sure to give the supply
capacitors adequate time to discharge before accessing the electronics area. This power is also provided to the
discharge terminals on the laser tube itself. Your laser shipped with silicone terminal covers that prevent access
to bare wiring—notify Full Spectrum Laser support and immediately cease operations if these covers ever slip and
expose bare wire.
5TH GEN HOBBY LASER USER’S MANUAL

Fire Safety
Laser cutting and engraving systems represent a significant fire hazard due to the extremely
high temperatures generated by the laser beam. While the objective of most cutting and
engraving operations is to vaporize material without burning, most materials capable of being
cut or engraved are inherently combustible and can easily ignite. Usually this is a small flame
of burning material issuing from the cut zone which self extinguishes due to the air assist or
de-powering of the beam. However, it is possible for the flame to propagate and set fire to the
machine and threaten its surroundings.
Experience shows that vector cutting with the laser has the most potential to create an open flame. Acrylic in all its
different forms has been shown to be especially flammable when vector cutting with the laser. Please also be aware
that stacking materials (especially organic materials such as paper) can lead to increased risk of flame propagation or
work piece ignition.
Please read the following warnings and recommendations and follow them closely at all times!
•
NEVER leave the laser system unattended during operation.
•
KEEP the area around the machine clean and free of clutter, combustible materials,
explosives, or volatile solvents such as acetone, alcohol, or gasoline.
•
ALWAYS keep a properly maintained and inspected 5lb or larger fire extinguisher on hand.
Full Spectrum recommends a Halogen fire extinguisher or a multi-purpose dry chemical
fire extinguisher. Halogen extinguishers are more expensive than a dry chemical, but offer
certain advantages should you ever need to use an extinguisher. The Halogen extinguisher
discharges a clean, easily removable substance that is not harmful to the mechanics or
wiring of the laser system. The dry chemical extinguisher discharges a sticky, corrosive
powder that is very difficult to clean up.
•
ALWAYS use air assist when vector cutting.
•
BE CAREFUL when vector cutting. Many materials have the potential to burst suddenly into
flames – even materials that may be very familiar to the user. Always monitor the machine
when it is operating.
•
KEEP YOUR LASER SYSTEM CLEAN – A build up of cutting and engraving residue and
debris is dangerous and can create a fire hazard. Keep your laser system clean and free of
debris. Regularly remove the cutting grid to clean any small pieces that have gotten stuck or
fallen through.

5TH GEN HOBBY LASER USER’S MANUAL
Setting Up Your Laser System
Setup of the Hobby Advanced laser usually takes less than 30 minutes, but there are a few things you will need
to take care of before it arrives:
•
Purchase distilled water for cooling the laser. Your laser comes with a pump and tubing for circulating the
water through the tube and back into a reservoir. Please make sure to only use distilled water—neither
filtered nor deionized water will work and tap water will cause deposits that can destroy your tube and
void the warranty.
•
Purchase a container to act as a reservoir for the distilled water. Be sure to check the container regularly
to ensure that the water remains clean and deep enough to cover the pump.
•
If you did not purchase an exhaust system from Full Spectrum, you will need to purchase and install one.
You may need a contractor to install the exhaust. This must be done prior to installation of the laser
system.
Once your laser has arrived, you will need to do the following to set up your machine:
•
Remove the laser and accessories from the box
•
Connect the exhaust, cooling and air assist systems
•
Remove the zip ties (3) that secure the drive belts during shipping
•
Remove the zip tie that secures the laser head
•
Connect electrical power
•
Connect the laser to your computer using an Ethernet cable
•
Install the latest version of RetinaEngrave (download information can be found in the shipping box)
NOTE
Please do not throw away the laser’s box and packaging, you may need it later.

Attaching the Focus Lens Assembly
The focus lens assembly (1) is pre-installed at the factory. It attaches to the focus head using one M3 thumbscrew
and two M3 spring washers. Attach the air assist tube to the push-to-connect connector (2) once the head has been
secured. Run a job with the laser OFF to verify the air tube will not interfere with the beam path or rub against the X
rail while engraving.

Connecting the Exhaust
It is mandatory that an exhaust blower is connected and operating whenever you run a job on your laser. The exhaust
blower removes smoke and fumes from the case and exhausts them to the outside of the building. You should never
operate your laser without a working exhaust. Full Spectrum recommends exhaust systems capable of 60-100CFM.
Keep in mind that exhaust systems with high flow rates may require fixtures for thin materials.
CAUTION
It is important that either rigid or flexible metal ducting be used in the exhaust system. Any type
of “soft” ducting is potentially flammable and should be avoided.
In the United States flexible aluminum ducting can be acquired from the following locations:

Exhaust Blower Connection
You will find a 4” (100mm) exhaust flange with the accessories for your laser. The flange must be attached to the
rear of the Hobby Advanced chassis in order to connect an exhaust blower.
Secure the exhaust port using the included screws and nuts.
Once the exhaust flange is installed, use flexible metal tubing to connect the laser system to the exhaust
system. Check your system for leaks—most can be remedied with duct tape. Please be aware that the
protective housing is not designed to be air-tight; the front grill is designed to allow an exhaust system to draw
fresh air through the work area.

18
Connecting the Water Pump and Air Assist
Compressor
Your HL40-5g laser uses a water-cooled continuous beam CO2 laser tube. The tube requires a flow of room
temperature water to regulate the temperature of the resonance chamber. Your purchase includes a water pump for
cooling the laser tube. A low-flow air compressor for vector cutting gas assist is available as an optional accessory.
CAUTION
NEVER FIRE THE LASER WITHOUT A CORRECTLY CONNECTED AND POWERED WATER PUMP.
FIRING THE LASER WITHOUT TURNING THE PUMP ON OR, WORSE, WITH NO WATER IN
THE SYSTEM, WILL SEVERLY DEGRADE OR DESTROY YOUR LASER TUBE AND VOID YOUR
WARRANTY.
We recommend that you attach the laser and
water pump to a power strip and use that
to control the mains power to the unit—this
ensures that the water pump is always on when
the laser is powered.
Please make sure that there are no air bubbles
inside of the water jacket of the laser tube. Air
bubbles can create local hotspots in the lasing
chamber and reduce the lifetime of your tube. If
present, water bubbles typically migrate to the
electrodes on either end of the tube. You should
visually inspect the laser tube to make sure that bubbles are not present; slightly tilting the laser while powering on
the circulation pump is usually sufficient to remove bubbles.
The tube is cooled by a circulation pump. The pump must be submerged in a container of distilled water (distilled
water is available from any grocery chain—most customers use a 5gal paint bucket as the reservoir) with one of the
two provided silicone tubes being connected from its output to the Water Inlet fitting. The other tube is connected to
the Water Outlet fitting and is left to drain back into the reservoir.
5TH GEN HOBBY LASER USER’S MANUAL
19
The water inlet and outlet are the two barbed connectors on the rear of the laser to the right of the exhaust flange.
The left one is the water inlet and the right is the water outlet.
Air is used as a pressurized gas to assist in cutting and engraving operations. The pressurized air is critical to safe
and efficient cutting operations as it not only helps cut through material more quickly, but also helps prevent the
formation of flames.
On the far right side of the machine is a push-to-connect fitting for the air assist input. Simply push the included ¼”
plastic tube into the connector (press on the plastic flange while pulling on the tube to remove it). Make sure that the
other end of the tube is connected to the air compressor.
THIRD-PARTY AIR ASSIST SYSTEMS
If you choose to attach your laser to a 3rd party air compressor, make sure to use at least one stage
of air drying and air cleaning (5 micron filter recommended) and limit the input pressure to no more
than 30psi. Low-quality compressed air can damage your focus lens.
20
Connecting Electrical Power
The Full Spectrum Hobby Advanced Laser System and available accessories are configured to accept 110VAC at
60Hz. 220VAC units connect to power through an included converter (single-phase 220VAC).
The electrical cord is found among the accessories. The power cord plugs into a C14 power receptacle located on the
right side of the machine in the lower rear. The laser system itself draws approximately W of power and can be run off
of most circuits without modification. However please be aware that the accessories will increase the circuit load; the
most significant power draw usually comes from the blower/exhaust system. Consult the manufacturer’s information
and manual for the operating parameters of your exhaust system.
NOTES:
•
POWER ON/OFF: the laser’s power is controlled by the large red button (e-stop)
located on the top of the case in the far right. This is a normally-open twist to release
button. To power the laser down, simply press the button down until it locks. To
power the laser up, twist the button clockwise according to the indicating arrows on
the surface of the button.
•
The laser system is equipped with a fuse on the power inlet to protect the machine
from surges or short circuits. The fuse is user-changeable (machine ships with 10A
fuse installed).
•
IN CASE OF A BLOWN FUSE: determine the cause of the overload before
replacement to protect the machine from damage.
•
CAUTION: do not replace the installed 10 amp fuse with a fuse of a higher rating.
This will void your warranty and the electronics will not be adequately protected from
surges or short circuits.
5TH GEN HOBBY LASER USER’S MANUAL

Connecting the Laser to your Computer
All Full Spectrum Laser Systems are designed to be used with either 32 or 64 bit versions of Windows 7. Full
Spectrum Laser recommends a system with the following minimum specifications:
Intel® Core™ or AMD Athlon™ II processor
Microsoft® Windows® 7 64-bit with Service Pack 1
6GB of RAM
The Hobby Advanced can connect to your computer via either Ethernet or USB (but not both simultaneously). Full
Spectrum includes an Ethernet cable in the laser accessories and recommends the use of Ethernet cables as USB is
more prone to electrical interference.
Your laser must be connected to your computer in order to download jobs. The laser can store jobs in its onboard
memory while powered, however loss of power will cause stored jobs to be lost. If you purchase and install a miniSD
card, you can download jobs to your laser and run them without a computer attached (however you will not be able
to alter the job settings from the laser control panel). Because an SD card is not volatile memory, jobs are stored
between power cycles.
NOTES:
•
If your laser is located more than 6ft from your computer, you will need to use the
Ethernet connection.
•
Connecting via Ethernet while the power is on requires you to power cycle your
machine in order to obtain an IP address.

Quick Start &
Setup
This section is the next step to ensure that your laser is working properly
5TH GEN HOBBY LASER USER’S MANUAL
Overview
Now that you have set up your laser and accessories and have installed the control software, the next step is to
ensure that your laser is working properly. The tube test and mirror alignment procedures should take less than
30 minutes and will ensure that your laser is performing optimally. Your laser’s main power is controlled by the
twist-release switch on the top of the case.
The first thing we are going to verify is that your laser tube did not crack during shipping. This should take less
than 2 minutes. The second test will check the mirror alignment and if necessary, adjust the mirrors so they are
once again aligned. The laser’s mirrors are aligned during assembly at our location, however shipping subjects
the laser system to a great deal of vibration which can cause the mirrors to vibrate slightly out of alignment.
These tests require the following tools and materials:
•
Scissors or small wire cutters (for removing axis zip ties.)
•
Thermal paper (This is the same paper that receipts are printed on. Used receipts work.)
•
Masking/painters tape (For taping the thermal paper to mirrors and apertures.)
•
2mm hex key (For adjusting mirror angles. Included in accessories.)
•
2.5mm hex key (For adjusting mirror mounts and angles. Included in accessories.)
Before we begin testing the laser, we need to free the motion system from its shipping restraints and remove the
accessories from the work area. The accessories are zip-tied to the front beam attenuator—cut the zip tie and
remove the accessories. The motion system is restrained by 6 zip ties: one on the X axis drive belt, two on each
Y axis drive belt and two securing the head slider. Carefully cut the zip ties, avoiding damage to the drive belts.
The focusing sub-assembly is also restrained by zip ties; they must be cut in order to perform alignment.

Laser Tube Test
In this test we are going to tape a piece of thermal paper between the laser tube aperture and the beam
combiner aperture and then test fire the tube.
1. Make sure that the proper accessories are attached and engaged (water pump)
2. Open the work area cover.
3. Take a piece of thermal paper and tape between the Beam Combiner and mirror 1 with the sensitive
(shiny) side facing the laser tube output. Alignment is not critical, but make sure that there is a large
enough white space that can capture the beam output; the beam is approximately 5mm in diameter and
will exit from the center of the tube.
4. Close the cover.
5. Place the laser into test fire mode (FS/Z button, toggle until menu reads “Align Mode”.
6. Press the Test Fire button.
7. A circular black mark with diffuse edges should appear on the thermal paper. If there is interference, the
mark will be occluded and/or have a very sharp edge. If this is the case, your tube is working but has
come out of alignment.
You should hear a ‘click’ and/or see a plasma arc inside the tube (may require more than one button press).
The click is from the power supply switching rapidly on then off for the test pulse. If you observe either of these
actions but no mark on the thermal paper, the paper was most likely reversed or incorrectly placed. If you do not
mark the paper and are not observing a noise during a test fire attempt, it is possible that the cover interlock was
not properly engaged; try shifting the cover or magnet closer to the sensor. If these solutions do not solve the
problem, please contact technical support at support@fullspectrumlaser.com

26
Mirror Alignment
Your laser was aligned during assembly and test in Las Vegas—the CO2 beam and Alignment Laser beams were
matched to follow the same path through the mirrors and fire down the center of the focusing head. However,
shipping is a high-vibration environment and it is sometimes necessary to re-align mirrors. Before we go through a full
re-alignment process, let’s check and see what the current alignment is:
ALIGNMENT TEST
1. Take a piece of thermal paper and place it above the lens on the focusing head, covering the aperture. Tape
two edges so that the paper will stay relatively taut over the hole. Press your finger firmly along the edge of
the aperture to make a mark on the thermal paper to show the aperture’s outline.
2. Jog the laser to the upper left corner.
3. Close the lid and test fire.
4. Observe the location of the mark on the thermal paper.
5. Jog the gantry halfway along the Y axis towards the lower (front) left corner. Test fire and observe the mark
6. Jog the gantry the remainder of the way along the Y axis and test fire at the lower left corner and observe.
7. The burn mark should be relatively close to the center and should not “walk” after jogging the laser head.
If there was a great deal of variation in the location of the burn marks (more than 2mm of drift) you will need to align
your laser. We recommend first aligning the invisible cutting beam with the visible Alignment Beam—this saves a
great deal of time lost in opening and closing the lid for safe access while firing the laser. The procedure for this is the
following:
ALIGNMENT PROCEDURE
The New 5th Generation Hobby laser has an integrated beam combiner which greatly simplifies beam alignment.
The general procedure is to first align the red beam with the invisible beam then use the red beam as the primary
indicator for alignment.
1. Put a piece of thermal paper on mirror #1.
2. Press the UNLOCK button on the laser control panel. In the unlocked state, you can move the laser head
around by hand and fire test dots using the TEST FIRE button.
3. Close the lid then press the TEST FIRE button on the laser control panel. A black dot should appear on the
mirror. Check that this dot is round and not clipped. You may need to press the test fire button several times
5TH GEN HOBBY LASER USER’S MANUAL
27
to get a dot. In the unlikely case the dot is still clipped after multiple test fires, the tube may be sitting at an
angle causing it to hit the beam combiner. Adjust one of the clamps of the laser tube to move the tube down
so it is not clipped by the beam combiner. This should not happen normally unless you changed the tube so
contact FSL tech support for more details.

4. Move the X gantry (the long black bar) down to the lowest Y position as shown in the following picture. Put
a piece of thermal paper on location #2. Fire a test pulse and observe where the black dot appears on the
thermal paper.
5. Without moving the gantry and without touching any of the mirrors, adjust the red dot pointer so that the red
dot overlaps with the black dot. Do this by adjusting the screws that hold the red laser in place.
Figure 6 - Revision 2 Diode Mount
28
6. Once the red dot overlaps with the black dot, the red is travelling along the same path as the invisible laser
beam and can be used to align the rest of the laser instead of relying on the invisible black dot.
Adjust beam combiner (BC) screws until
red dot is same height then twist BC
until both overlap

7. Move the X gantry to the top Y position. Fire another black dot onto the thermal paper. You should now
have two black dots (one from the upper Y position and one from lower Y position). Move the X gantry up
and down and verify that the red dot tracks from one black dot to the other black dot.
8. Move the X gantry to the lowest Y position. The red dot should now overlap with one of the black dots.
Adjust mirror #1 until the red dot is in the middle of the two black dots.

9. Use a fresh piece of thermal paper and fire a test dot with the X gantry still in the lowest Y position. Move the
X gantry to the top position and fire another test dot. Now the two black dots should be closer together than
in step #6.
10. Move the X gantry back to the lowest Y position. Now adjust the red dot until it moves to the center of the
two black dots.
11. Repeat the process of firing two black dots on the top and on the bottom Y positions and adjusting mirror #1
to move the red dot to the center of the two black dots until the two black dots from the top and bottom Y
positions are centered on top of each other.
The idea is that when the laser is not aligned, you will have two black dots from the test fires in the top and bottom
positions. The red laser pointer is aligned with the invisible laser pointer so gives you immediate feedback on the
mirror adjustment. By adjusting it into the middle of the two black dots, you are splitting the error difference. Usually
after 1 or 2 iterations, the black dots will be exactly on top and this axis is aligned. The goal is to have the two black
dots overlap exactly. IT IS NOT NECESSARY THAT THE DOTS BE IN THE CENTER OF THE MIRROR BUT THEY
SHOULD BE SOMEWHERE ON THE MIRROR. Mirror #1 is now aligned.

12. Once the mirror #1 is aligned, we will adjust mirror #2. Put a piece of thermal paper on mirror #3. Using the
red dot, adjust the mirror until the red laser is somewhere on the mirror.
13. Move the laserhead to the far right position. Fire a test dot here producing a black dot. The red and black
dot may be off slightly because the distance travelled by the laser beams is longer so any small errors are
amplified. Without touching any of the mirrors, adjust the red dot to overlap with the black dot through the
screws on the red laser diode mount or twisting the red laser diode mount.
14. Put on a new piece of thermal paper. Move the laserhead to the far left and fire a black dot. Move the
laserhead to the far right and fire a second black dot.
15. Now you should have two black dots on the thermal paper and the red dot. Verify as you move from the left
side to the right side that the red pointer tracks between the two black dots.
16. Move the laserhead to the far right. The red laser dot should overlap with one of the black dots. Adjusting
only mirror #2, move the red dot between the two black dots.

17. Replace with a new piece of thermal paper and fire dots in the far left and far right positions. Again move to
the far right position then adjust the red dot between the two black dots. Repeat until the two black dots are
exactly on top of each other. Mirror #2 is now aligned.
18. Once mirror #2 is aligned, put a piece of thermal paper on top of the lens. Adjust the screws on mirror #3
until the red dot is in the center of the lens. Fire a black dot into the thermal paper.
19. Move the laser head around and verify the red dot does not move away from the black dot anywhere on the
laser bed. The closer you get the dots stationary, the better aligned the laser will be. You can fire black dots
at the 4 corners of the laser bed and verify none of them are more than 2mm away from each other.
Adjust mirror #3
until red dot centered
Congratulations, your laser is now aligned!
Focusing
Focusing the Hobby Advanced Laser is quick and easy. Your laser included a billet sized for the included 2-inch
focal length lens. To focus for engraving or cutting, simply place the billet on the top of the engraving plane and then
release the locking mechanism on the focus head until the air assist nozzle rests on top of the billet. Then re-tighten
the sliding head and remove the billet from the work piece.

Laser Head Adjustment
Proper laser head adjustment is critical for high accuracy. The two upper wheels of the laser head have fixed axles
and the two bottom wheels are mounted through eccentric spacers. When the eccentric spacers are turned, they
tighten the bottom wheels against the underside of the black X axis rail. Too much tension and the wheels can bind
up when doing high speed raster or rapid moves. Too little tension and you can see some slop in the cutting. Two
special wrenches are included to adjust the wheels.
ECCENTRIC SPACER ADJUSTMENT INSTRUCTIONS
1. Adjusting the eccentric shafts is done by first
loosening the locking nut which is pressed
against the spring washer and the eccentric
shaft. Use one of the included adjustment
wrenches to hold the eccentric spacer in place
while using the second to loosen the nut.
2. With the locking nut loosened, you can use one
wrench to turn the eccentric shaft.
a. Depending on the initial location of the
eccentric, a clockwise turn can either tighten
or loosen the wheel.
3. Remember to use the two wrenches to retighten
the locking nut after you are happy with the
eccentric nut position.
Figure 7 - Eccentric Spacer Adjustment
PROPER WHEEL TENSION INSTRUCTIONS
The proper tension should be tested as follows:
1. Unlock the motors or turn off the machine. Grip the laser head with one hand. You should be able to turn
each of the wheels relatively freely with the other hand even with the laser head held in one place. If you
can’t turn each wheel without moving the laser head, likely the tension is too high and one or both eccentric
wheels need to be loosened.
2. Let the laser head go. Turn each of the wheels and the laser head should move. If the wheels are
freewheeling then the tension is too low and the eccentrics should be tightened.
32
3. Check if there is any front to back tolerance in the laser head assembly. This can be tested by gently twisting
the laser head about the Z and X axes of the machine. There should be minimal wobble to ensure the laser
head doesn’t move when the laser head rapidly changes direction. A small amount of looseness on the head
is required for proper operation.
Ideally the wheels should be tight enough so if they rotate then they move the head but not tight enough that
they introduce too much friction. The above wheel test is an excellent test of balance between these two.
BELT TENSION
The belts of your laser should be relatively tight and have no sag; you should be able to pluck any of the belts and
it should vibrate back to stiffness. Ideal belt tension is achieved by applying moderate to high pressure with one’s
hands to the idler pulley—no extra leverage is needed. The X idler pulley is held in place with an M4 hex nut and can
be adjusted with the included eccentric adjustment key. The Y idlers are mounted on two L-shaped brackets and held
with two M4 cap screws. The M4 cap screws require a 3mm hex key to adjust.

Quick Start
Your Full Spectrum laser system is ready to use if you have read the manual to this point and followed all of
the foregoing instructions. Please remember to use caution while operating the laser and make sure that all
accessories are functioning properly before running any job. The following instructions provide a general workflow
for taking an original design and turning it into a laser cut part:
1. Create your artwork/design in the software program of your choice (e.g. CorelDraw) or use the Design View
tab of RetinaEngrave.
2. Turn on the machine and accessories and wait for it to find an IP.
3. Once the machine has an IP (approx. 30s), launch RetinaEngrave.
4. Place your piece of sample material on the honeycomb.
5. Focus the laser head onto the sample piece.
6. Close the cover.
7. From CorelDraw, call up the print menu.
8. Select the “Full Spectrum Engineering” Driver.
9. If the “Pre-flight check” fails, check that both your document page size and printer page size match the size
of the work area, and that no artwork Is outside the boundaries of the page.
10. Once the pre-flight check is clear, continue printing to the software.
11. Your design will be loaded and then rendered by RetinaEngrave under the default raster tab.
12. Once you have set the power levels and layer ordering to your liking, you can run the job. If you plan to run it
often, you can save the project file to a location on your hard drive.

POSSIBLE CAUSE
SOLUTION
This problem is usually caused by
a loose rear coupler or an uneven
belt (after a Y-axis crash or skip).
Re-squaring the Y axis is not difficult,
but it is very helpful to have an extra
pair of hands.
Steps:
1. Using the 2mm hex key, loosen the motor flex
coupling (2 screws)
out of square (lines are
straight, but angles are
wrong)
39
2. Make sure that the middle flex coupling is tight
(avoid putting pressure on the Y shafts)
3. Take two known-length standards of equal size
(1-2-3 blocks work well) and place them at the
front of the machine on either Y-rail, flush with the
interior wall of the top panel.
4. Slide the gantry forward so that both left and right
risers are in contact with the blocks.
5. Maintaining forward pressure on both sides of the
gantry, re-tighten the motor flex coupling.
This is usually caused by the Y axis
eccentric cams being over-tightened.
The normal motion along the Y axis
should be smooth and not require
too much force when the laser is off
or unlocked.
Gantry jams/skips during
Y moves
This problem is usually caused by a
mis-adjusted laser head.
Vector cut lines are not
straight
Slowly move the Y axis from the rear of the laser to
the front. If you feel bumps or sticking points, the
eccentric cams are over-tightened. Loosen the cams
until the Y motion is smooth.
The wheels of risers 2 (left slider) and 3 (right slider)
should be contacting the Y rails in the following
manner:
•
Eccentric wheels should have good contact with
bottom channel
•
One of the upper, fixed wheels on each side
should have good contact with the upper channel
•
One of the upper, fixed wheels on each side will

APPENDIX A: ROTARY ATTACHMENT SETUP AND INSTALLATION
OVERVIEW
Thank you for purchasing the Full Spectrum Laser Hobby Advanced Rotary Attachment. The rotary attachment
is capable of engraving on objects from 0.25in diameter. This Appendix explains the typical install method of the
rotary attachment into a 5th Generation Hobby Laser (HL40-5g Hobby Advanced). Once you have unpacked your
rotary attachment, you will need to connect it to your laser’s RetinaEngrave PRO controller before running any jobs.
ROTARY ATTACHMENT INSTALLATION
Once you have unpacked your rotary attachment, begin the installation process by placing it into the work area
of your laser (Figure 10 - Rotary Attachment). The rotary attachment is a friction-wheel type—objects rest on two
driven and two idling wheels and are turned to engrave an image onto the surface of a cylindrical object.
Figure 10 - Rotary Attachment
Because some small objects are very light, the rotary attachment has two hold-down plates
to force light objects into contact with the drive wheels.
5TH GEN HOBBY LASER USER’S MANUAL
43
The rotary attachment works by translating Y motion along a cylindrical surface. With the laser off, place the rotary
attachment into your laser’s work area, and disconnect the Y motor from the RetinaEngrave PRO control card
and connect the rotary attachment motor in its place. Note the orientation of the connector and the wiring (Figure
11 – Rotary Attachment Motor Connection), this orientation should be maintained when connecting the rotary
attachment to the control card.
Once you have connected your rotary attachment, you can activate your laser and move the rotary attachment and
laser head into a position to engrave on your work piece. The red dot should be in the same vertical (X-Z) plane as
the center axis of the work piece.
Figure 11 – Rotary Attachment Motor Connection
Keep in mind that Y axis motion is now sent to the rotary, so you may need to unlock the
laser head and move the gantry by hand.
44
USING THE ROTARY ATTACHMENT
The rotary attachment is designed to be used within the laser case, however its maximum engraving diameter can
be increased by modifying your laser system’s bottom panel. Please be aware that any system modifications must be
performed by an authorized technician and in accordance with all applicable state and federal laws.
ALIGNING YOUR ROTARY ATTACHMENT
The best way to align your rotary attachment with the laser head is to build a jig that uses the frame as a reference.
1. A quick procedure to visually align the rotary
attachment follows.
2. Focus the laser head onto the rear frame member of
the rotary attachment on the far left.
3. Slide the laser head to the right, keeping the red
dot in the same relative position on the rotary frame
member as you go.
5TH GEN HOBBY LASER USER’S MANUAL
FOCUSING YOUR ROTARY ATTACHMENT AND LEVELING THE WORK PIECE
Rotary engraving should be carried out along the topmost portion of your circular work piece co-planar with the
work piece axis. Focus the laser with the included billet. It is important that your work piece be level along its
length—a small carpenter’s level is very helpful. The following illustrates the steps:
1. Align red dot on work piece.
2. Laser head focused.
3. Laser focused and work piece leveled.

APPENDIX B: LASER TUBE REPLACEMENT
OVERVIEW
This Appendix provides procedures and a walkthrough to replace the laser tube on your Hobby Advanced Laser.
Please carefully read all instructions before beginning the replacement procedure as there are several critical steps
which must be properly followed to avoid breaking the laser tube. The included pictures show how to properly
connect wires to the tube’s electrodes and secure the connections.
REQUIRED PARTS AND TOOLS:
•
FSL 40W replacement tube (Part Number: 420153-01)
•
Wrench (for M5 hex nuts)
•
Scissors/wire cutters
•
Large zip ties
•
2mm hex key for removing back panel of laser (included with accessories)
•
6.5mm ID silicone tubing (included with FSL replacement tube)
•
RTV Silicone Adhesive Sealant (available at your local hardware store)
•
Teflon/PTFE tape (at least 2 10in lengths). Also called plumber’s tape; blue PTFE tape is ideal (available at
your local hardware store).
CAUTION
•
Pulling on the tube wires will break your laser tube at the neck
•
The water connections are very fragile, DO NOT pull or force the connection tubes—
gently work the tubes off of the connectors.
•
The capacitors in the power supply retain power even after turning the laser off. To
ensure your safety, turn off the laser, remove the power cord and wait at least 1 hour
before accessing the power supply.
48
REPLACEMENT PROCEDURE
SWITCHING THE TUBE
The best way to align your rotary attachment with the laser head is to build a jig that uses the frame as a reference.
1. Power off and unplug your unit. Wait at least 1 hour for capacitors to discharge.
2. Disconnect water from rear connectors. Use the small piece of tubing that shipped with your laser to shunt
the two water bulkheads together.
3. If necessary, move your laser so that you have at least 1ft of table working space to access the rear of the
unit. You will be removing the rear panel to access the tube.
4. Using a wrench, remove the 4 M5 hex nuts from the posts on the rear of the laser
5. Using a 2mm hex key, unscrew the 5 lower M3 6mm button head socket screws and 2 upper M3 6mm
button head socket screws.
6. Carefully remove the rear panel and lay flat on your work surface.
7. Carefully remove the silicone sealant and tubing to expose the BLUE ground wire (located at the tube
aperture).
8. Unwrap the BLUE ground wire from the tube terminal.
9. Hold the BLUE ground wire about 8 inches from the exposed end. Move the exposed end to the RED
POWER terminal. If there is any residual voltage in the capacitors, there will be a spark as it grounds to
the BLUE wire. DO NOT hold the blue wire near the exposed end while doing this. NEVER perform this
procedure while the laser’s power cord is connected. The waiting period should have dissipated any
residual charge, but take extreme care during this procedure.
10. Carefully remove the silicone sealant and tubing to expose the RED power wire (located at the rear of the
tube).
11. Unwrap the RED power wire from the tube terminal.
12. Remove the two water tubes from the inner bulkheads.
13. Remove the water tubes from the laser glass bulkheads—please exercise caution as using to too much
force can break the bulkheads and prevent a sharp glass hazard (and will also make your tube unusable).
14. Remove the laser tube mounts from the panel. Not the orientation of the tube relative to the holders.
15. Remove the mounting U-bolts from the rubber tube holders.
16. Remove the tube from the rubber holders.
17. Set aside the old tube.
18. Place the new tube into the rubber holders in approximately the same orientation as the old tube.
5TH GEN HOBBY LASER USER’S MANUAL
49
19. Attach the U-bolts to the rubber holders and place the tube back onto the rear panel.
20.Exercising caution, thread the M5 hex nuts onto the U-bolt posts and make snug (but not yet tight) with the
rear panel.
21. Carefully attach the water tubes to the proper laser connection bulkheads. Make sure that the water tube
routing and locations match the original configuration
CONNECTING THE TUBE TO THE POWER SUPPLY
1. Straighten the exposed wire on the red lead. Twist the wires together.
2. Slide one piece of silicone tubing onto the red lead .
3. Wrap the exposed portion of the red lead tightly and securely around the positive electrode—reflector end,
opposite the aperture.
50
4. Thread Teflon tape around the neck of the laser tube.
5. Tightly wrap one end of the Teflon tape several times around the electrode.
6. Bring the opposite side of the Teflon tape around the neck of the laser tube and around the inside of the
electrode.
7. Wrap the Teflon tape tightly around the electrode.
5TH GEN HOBBY LASER USER’S MANUAL
51
8. Knot the Teflon tape tightly around the electrode (Figure 66 and Figure 67). Repeat. Trim Teflon tape.
9. Slide the silicone tubing onto the electrode.
10. Fill the silicone tubing with silicone sealant.
11. Allow the silicone to dry.
12. Repeat steps 1 through 8 for the BLUE ground wire that attaches to the electrode nearest the tube aperture;
it is not necessary to insulate the ground wire with silicone tubing or sealant.
